日本高炉降硅的历程大致可分为两个阶段:在七十年代为第一阶段;在八十年代则为第二阶段。文中概括了日本高炉降硅的途径。笔者提出,根据日本经验可以得出几点启示:①我国高炉降硅的起点较高,目前希望炼钢生铁硅量在0.4～0.6％之间;②高炉降硅应在提高利用系数和节约燃料此的大前提下进行;③焦炭灰份是SiO的主要发生源;④提高[Mn]量可以降硅;等等。
Japan’s blast furnace to reduce the process of silicon can be broadly divided into two stages: in the seventies for the first stage; in the eighties for the second stage. The paper summarizes the ways to reduce the silicon in Japanese blast furnace. The author suggests that based on the experience of Japan, we can draw some enlightenment: First, the starting point of lowering the blast furnace in our country is high, and we hope that the amount of pig iron in the steelmaking range from 0.4 to 0.6%; ② The blast furnace should reduce the silicon utilization factor and save fuel Under the premise of this; ③ coke ash is the main source of SiO; ④ increase [Mn] can reduce the amount of silicon; and so on.
